Fiorentina GM Joe Barone cannot guarantee Nikola Milenkovic staying this summer.

However, he insists they want to keep the Serbia defender.

Barone told TMW: "(Rocco) Commisso and I want Milenkovic to stay, we are a good group.

"But it won't be easy, we'll see what happens if someone comes knocking saying they are interested in him. We want him to stay.

"The more days pass the better, but I can't give any guarantees."
